Efficient production of male Wolbachia-infected Aedes aegypti mosquitoes enables large-scale suppression of wild populationsJ. E. Crawford, D. W. Clarke, V. Criswell, M. Desnoyer, D. Cornel, B. Deegan, K. Gong, K. C. Hopkins, P. Howell, et al., Nature Biotechnology, 38:482-492. 2020.
The range of the mosquito Aedes aegypti continues to expand, putting more than two billion people at risk of arboviral infection. The sterile insect technique (SIT) has been used to successfully combat agricultural pests at large scale, but not mosquitoes, mainly because of ... |

The value of existing regulatory frameworks for the environmental risk assessment of agricultural pest control using gene driveJ. Romeis, J. Collatz, D. C. M. Glandorf and M. B. Bonsall, Environmental Science & Policy, 108:19-36. 2020.
The application of (synthetic) gene drives is a powerful tool to control populations of insects that are agricultural pests, vectors of diseases, or a threat to biodiversity potentially leading to the local or global eradication of a species. The potential use of gene drive ... |
